' 'ras'rnn'me nnvma Application filed Kai-ch12, 192a. Serial No. 2e1',1e1.

My invention relates to improvements'in' ,fastening devices, and itconsists in the combinations, vconstructions, and arrangements herein described and claimedr g,

An object of my invention is to provide a fastening device of the type employing a' stationary arm and a movable arm, and in which means is employed for. preventing the rotation of the fastening device after ithas been-inserted in a buttonhole or the like,

thereby providing a device which cannot be- I come accidentally removed from the buttonhole. i

A further object is to provide a fastening device in which the spring means for moving the movable arm into locked engagement with the stationary arm is contained within a housing which is disposed within the but- 'tonhole when the fastening device 1s passed through the latter, thereby rovidinga device which is relativel simp e, compact, du-

- rable and eflicient for t e purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a plan view of my device show ing the manner in which it may be em-' p10 ed Eh re 2 is a sectional view taken substantially along the line 2-2 of Figure 1,

Figure 3 is a sectional detail view of a modified form of my device, and

Figure 4 isan elevation taken at right an les to the device shown in Figure 3..

r n carr ing out In invention, I make use of arms and B, the arm A bein firmly secured to a center post or rivet'l. he arm A may be welded to the rivet 1. The rivet 1 is secured to a disc 2 which is rigidly retained by a base portion 3 see 1 The arm B is provided with jecting within a spring housing 5. A

spring 6 is disposed within the housingband bears against one end of the sleeve *4 for normally holding the arm B in locked engagement with the arm A. Means for preventing rotation of the fastening device after it has been inserted in a Buttonhole 7 or the like consists in the provision of a pair of laterally extending arms 8. These arms may be welded to the housing 5 and gore 2. a sleeve por tion 4 rotatable about the rivet 1 and pro latter into locked eng to the brace member 2. g I claim:

withlug portions 9, as .shownin i The arms A "and B areprovided with recesses' 10- andll for interlocking when the the disc 2.- The arms Aand Bare rovided' movable arm B is disposed at right angles] to the arm A. I

From the foregoing tdescriptionof'the' various' arts of the device, the operation thereo may be readilyunderstood, :Wheil :1t is desired to insert the device'in the but tonhole 7 thelmovablearm B ispressed-in-Y w'ardly in the direction of the base for dis engaging the 'armB from the arm A and the arm B is then moved into longitudinal alignment with the arm A; [At this time the" i arms are passed through the buttonhole -7 i and the arm B is rotatedabout the" rivet 1 armsSare disposed within the buttonhole,

as shown in Figure 1, so that the fastenin device is firmly locked against rotation an is thereby prevented frombeeoming accidien tally removedfrom the buttonhole.

- In Figures 3 and 4, I have shown, a modified form of my device in which an arm-11 is secured to a rivet 1 supported by a flat like brace member 2'. The brace member 2 t is provided with a recess 12 vvithin which] the arm A may be disposed The brace member 2 is held against the arm A by means. of spring members '13. The brace member 2' passes throu h a slot in a disc f portion 14. Thus it wi l be seen that the;

brace member 2' is held against rotation,

but that it is held against the arm A by reason ofthe springs 13L a In operation, the brace member 2' may be moved against the springs 13 .for releasing the arm A, whereupon the latter may be moved into alignment with the brace member 2- and the device inserted: in a buttonhole and the arm moved for bringingthe f gement with respect 1.
